具体实施方式
参照附图,其中相同的附图标记表示相同的部件,图1示出了混合动力车的动力系11,包括发动机13,多模式混合动力变速器12,电子-液压控制系统10,以及最终传动件19。混合动力变速器12包括四个离合器C1,C2,C3,以及C4以及两个电动马达A和B。
参照图2A,控制系统10包括四个调整阀T1,T2,T3,以及T4和两个切换阀X和Y。图2B示出了切换阀X和Y以及图2C示出了调整阀T1,T2,T3,以及T4。调整阀T1,T2,T3,以及T4和两个切换阀X和Y中的每个都包括限定了多个口16的阀体14和可滑动地布置在阀体14内用于调节流体流入和流出口16的阀构件18。阀构件18在移动和未移动位置之间可滑动地布置在阀体14内。调整阀T1,T2,T3,以及T4和两个切换阀X和Y的阀体通过控制系统10和变速器12经由用于移动液压流体、机油等的相互连接的液体通道20的网络与变速器12的离合器C1,C2,C3,和C4流体连通。液体通道20连接到各个口16从而在阀体14内提供流体连通。因此,一些流体通道20将一些调整阀T1,T2,T3,以及T4和/或切换阀X以及Y彼此相互连接。其它的流体通道20将一些调整阀T1,T2,T3,以及T4与离合器C1,C2,C3,以及C4连接。
此外,控制系统10包括用于控制调整阀T1,T2,T3,以及T4和两个切换阀X和Y的多个螺线管S1,S2,S3,S4,S5,以及S6。螺线管S1,S2,S3,S4,S5,以及S6构造为使得每个螺线管S1,S2,S3,S4,S5,以及S6专用于相应的调整阀T1,T2,T3,以及T4或切换阀X和Y,以使阀构件18在调整阀T1,T2,T3,以及T4或者切换阀X和Y的阀体14内在移动位置和未移动位置之间移动,从而调节进入和离开相应调整阀T1,T2,T3,以及T4或切换阀X和Y的口16的流体。
流体经由泵22移动通过流体通道20,调整阀T1,T2,T3,以及T4,切换阀X和Y,变速器12等。泵22可以是传动泵,辅助泵等。多个回流通道24从调整阀T1,T2,T3,以及T4和切换阀X和Y的口16延伸出从而将调整阀T1,T2,T3,以及T4和切换阀X和Y与变速器12相互连接。流体以通常的低压力在回流通道24内流动。回流通道24延伸至每个马达A和B,用于在工作期间冷却马达A和B。与流体通道类似,回流通道24将调整阀T1,T2,T3,以及T4和/或切换阀X和Y中的一些与马达A和B相互连接。
变速器12通过″切换″或者接合不同的离合器C1,C2,C3,以及C4组合来改变最终传动件19上的输出转矩。控制系统10控制何时以及哪些离合器C1,C2,C3和C4接合或脱离。如图3和4所示,变速器12可以以四种不同的电子可变变速器(EVT)模式和三种不同的固定档位模式工作。控制系统10使用如图5A-14B所示的液压离合器控制策略,用于在这七种模式之间进行切换。如图1所示,行星齿轮装置30提供了在输入轴32与输出轴34之间的四种前进速度比或EVT模式。在EVT模式1中,离合器C1与C3接合。在EVT模式2中,离合器C1与C4接合。在EVT模式3中,离合器C2与C4接合。在EVT模式4中,离合器C2与C3接合。在固定档位1中,应用离合器C1,C3,C4。在固定档位2中,应用离合器C1,C2,C4。在固定档位3中,应用离合器C2,C3,C4。
控制系统包括用于操作控制系统10的电子部分的电子控制单元(ECU)36或控制器,以及用于操作控制系统10的液压部分的液压控制单元(HYD)。ECU与传统的数字计算机相结合,数字计算机可编程为控制系统的液压部分提供电信号从而建立离合器C1,C2,C3以及C4的接合与脱离。图2A更详细地示出了控制系统28。控制系统的液压部分包括诸如可变容积型泵这样的液压泵22,该液压泵22从贮存器40抽取流体,用于传递至流体通道20与调整阀T1,T2,T3,以及T4和切换阀X和Y。
控制系统10的电子部分或控制器包括螺线管S1,S2,S3,S4,S5,和S6,这些螺线管接收电子信号从而有选择地使阀构件18在调整阀T1,T2,T3,以及T4或切换阀X和Y的阀体14内的移动位置和未移动位置之间移动。这意味着,流体不同时通过调整阀T1,T2,T3和T4以及切换阀X和Y的所有口16。当阀构件18在阀体14内移动时,一些口16,以及对应的通道20被阻塞从而阻止流体的流动,而其它口16,以及对应的通道20被打开从而允许流体从一个通道20向相邻的通道20的流动。
如果停止向控制系统10提供动力,控制系统10包括离合器控制机构42,如图4所示,如果变速器10在四个EVT模式中的一个中工作,该离合器控制机构42向变速器10的当前工作模式提供液压默认值,或如果变速器10在三个固定档位模式中的一个中工作,则默认为下一最低EVT模式。此外,控制系统10提供防止或“切断”变速器10的离合器C1,C2,C3,和/或C4的不希望的切换顺序或接合的工作模式。
参照图4,两个阻塞的阀存在四种逻辑组合,如图3和4所示,其提供了四个工作区域。在第一逻辑组合中,切换阀X未移动而切换阀Y移动。在第二逻辑组合中,切换阀X和Y都移动。在第三逻辑组合中,切换阀X移动而切换阀Y未移动。在第四逻辑组合中,切换阀X和Y都未移动。工作区域是M1,全部可用,M3/G3/M4,以及M4。因此,当获得第一逻辑组合时,实现了M1工作区域,当获得第二逻辑组合时,实现了全部可用工作区域,当获得第三逻辑组合时,实现了M3/G3/M4工作区域,以及当获得第四逻辑组合时,实现了M4工作区域。
如果发生变速器控制器的动力损失时,螺线管S1,S2,S3,S4,S5,以及S6,离合器C1,C2,C3,以及C5的组合,以及切换阀X和Y的闭锁,允许变速器10锁定在当前工作模式或如果运行在固定档位时允许锁定在下一较低模式中。例如,参照图3和图4,如果变速器10在固定档位2中工作并且发生动力损失时,变速器10将锁定在EVT模式2即下一最低模式中。作为另一例子,如果变速器10在EVT模式2中工作并且发生动力损失时,变速器将锁定在EVT模式2中。因此,控制该机构为具有四个EVT模式和三个固定档位模式的多模式混合动力变速器10提供了安全工作的能力。提供了安全工作区域从而防止无意的模式-模式,模式-档位,以及档位-档位的切换,以及提供了在变速器控制器的动力停止状态期间锁定在当前工作模式中的能力。
流体在调整阀T1,T2,T3,和T4和/或切换阀X和Y的移动位置与未移动位置之间的流入或者流出运动导致了各个离合器C1,C2,C3,和C4的受控接合与脱离。具体参照图5A,6A,7A,8A,9A,10A,11A,12A,13A,和14A,存在用于各个离合器C1,C2,C3,和C4的接合和脱离的切换顺序。这意味着,从图5A所示的布置开始切换,并且离合器C1,C2,C3,和C4的接合和脱离的顺序分别经由图5A,6A,7A,8A,9A,10A,11A,12A,13A和14A进行。具体参照图5B,6B,6C,7B,8B,9B,10B,10C,11B,12B,13B,13C,14B,示出了变速器10默认的当前工作模式。因此,图5A-14B表示包括具有口16的阀壳体14的切换阀X和Y,以及相对于口16的阀构件18的位置用于允许流体在口16之间流入和流出。
具体参照图5A,当变速器10在EVT模式1中工作(其中,切换阀X未移动以及切换阀Y移动)并且停止了变速器10的动力时,变速器10默认至图5B所示的配置,当前工作EVT模式,为EVT模式1。
具体参照图6A,当变速器10在EVT模式1中工作(其中,切换阀X和Y移动)并且停止了变速器10的动力时,在切换阀Y退回(destroke)之前如果切换阀X退回,则变速器10默认为图6B所示的配置,EVT模式1,或者如果在切换阀X之前切换阀Y退回,则变速器10默认至图6C所示的配置,EVT模式2。
具体参照图7A,当变速器10在固定档位1中工作(其中,切换阀X和Y移动)并且停止了变速器10的动力时,变速器10默认至图7B所示的配置,下一最低工作EVT模式,EVT模式2。
具体参照图8A,当变速器10在固定档位2中工作(其中切换阀X和Y移动)并且停止了变速器10的动力时,变速器10默认至图8B所示的配置,工作EVT模式,为EVT模式2。
具体参照图9A,当变速器10在EVT模式3中工作(其中切换阀X和Y移动)并且停止了变速器10的动力时,如果切换阀Y在NO2闭锁之前退回,变速器10默认至图8B所示的配置,离合器C4空档,或者如果在Y退回之前NO2闭锁,变速器10默认至图9C所示的配置,EVT模式2。
具体参照图10A,当变速器10在EVT模式3中工作(其中,切换阀X移动以及切换阀Y退回)并且停止了变速器10的动力时,变速器10默认至图10B所示的配置,当前工作EVT模式,为EVT模式3。
具体参照图11A,当变速器10在固定档位3中工作(其中,切换阀X移动以及切换阀Y退回)并且停止了变速器10的动力时,变速器10默认至图10B所示的配置,下一最低工作EVT模式,EVT模式3。
具体参照图12A,当变速器10在EVT模式4中工作(其中,切换阀X移动和切换阀Y退回)并且停止了变速器10的动力时,如果切换阀X在C4闭锁之前退回,变速器10默认至图12B所示的配置,EVT模式4,或者如果在X退回之前C4闭锁,变速器10默认至图12C所示的配置,EVT模式3。
具体参照图13A,当变速器10在EVT模式4中工作(其中,切换阀X和Y退回)并且停止了变速器10的动力时,变速器10默认至图13B所示的配置,当前工作EVT模式,为EVT模式4。
具体参照图14A,当变速器10在EVT模式2中工作(其中,切换阀X和Y移动)并且停止了变速器10的动力时,变速器10默认至图14B所示的配置,当前工作EVT模式,为EVT模式2。
